Review: Samsung Sunburst
Bluetooth
Bluetooth worked well on the Samsung Sunburst. I was easily able to pair the phone with a Bluetooth headset and a set of stereo Bluetooth speakers. The phone has object push capabilities to transfer photos over Bluetooth. This worked fine on my Windows 7 machine, but I couldn't connect using my Mac.
Clock
There's a nice, large clock on the Sunburst's lock screen. You can also add clock and calendar widgets to the TouchWIZ homescreen. Or, you can just rely on the clear digital clock at the top of the screen, which is present in every application.
GPS
The Sunburst uses AT&T Navigator for turn-by-turn directions. The navigator app could be much more touch friendly, but definitely got the job done. It tracked me on my trip in and out of the big city with no trouble, offering a new route or traffic advice along the way, as needed. It's an extra fee for the subscription, but that's fairly standard, so this is one exception I would make if you want good directions on your phone.
Other Extras
The Sunburst doesn't get some of the newer AT&T feature phone options, like the Online Locker or the online Address Book, but it does get the AppCenter to download apps. These are mostly simple games and tools, but it's nice to have the option to expand a bit.
